Femoral head necrosis drilling

Femoral head necrosis and decompression is also called femoral head hip decompression. The surgical procedure is mainly applied to the early stage of avascular necrosis of the femoral head. The shape of the femoral condyle is normal. The necrotic death is limited to the front of the femoral head. There is no dead bone formation, no metaphysis change, and no subchondral fracture line. This surgical method is one of the main methods for the early treatment of femoral head necrosis, which can greatly alleviate the pain symptoms and delay the development of avascular necrosis of the femoral head. Treatment of diseases: femoral head necrosis Indication The surgical procedure is mainly applied to the early stage of avascular necrosis of the femoral head. The shape of the femoral condyle is normal. The necrotic death is limited to the front of the femoral head. There is no dead bone formation, no metaphysis change, and no subchondral fracture line. Contraindications 1, with systemic diseases, can not tolerate surgery. 2, local infection, not suitable for surgery. Preoperative preparation Regular use of antibiotics to prevent infection. Surgical procedure The femoral head is drilled in the large trochanter at the upper end of the femoral shaft. The number of holes is generally 1-3, in order to reduce the pressure inside the femoral head. complication Although this method can relieve pain within a certain period of time, it can not delay the development of the disease course, and even accelerate the speed of collapse: because the drilling itself is destroying the bone structure, weakening the pressure bearing capacity of the femoral head, and the pressure bearing capacity is weak. Microfractures cause irreversible collapse of the femoral head.
